crypto_blkcipher_encrypt — encrypt plaintext
| int crypto_blkcipher_encrypt ( | struct blkcipher_desc * desc, | 
| struct scatterlist * dst, | |
| struct scatterlist * src, | |
| unsigned int nbytes ); | 
descreference to the block cipher handle with meta data
dstscatter/gather list that is filled by the cipher operation with the ciphertext
srcscatter/gather list that holds the plaintext
nbytesnumber of bytes of the plaintext to encrypt.
Encrypt plaintext data using the IV set by the caller with a preceding call of crypto_blkcipher_set_iv.
The blkcipher_desc data structure must be filled by the caller and can reside on the stack. The caller must fill desc as follows: desc.tfm is filled with the block cipher handle; desc.flags is filled with either CRYPTO_TFM_REQ_MAY_SLEEP or 0.
